The bucket 22 may be configured as an external object as shown in fig. 9, and the unloading device 23 employs the unloading device 10 and the unloading device of the modified embodiment thereof, and further locks with the bucket 22 by the locking mechanism 13 of the unloading device 10, and further swings and is further installed and fixed with the bucket 22 by the installation guide mechanism 14 thereof, and since how the locking mechanism 13 is locked and how the installation guide mechanism 14 is matched with the external object (i.e., the bucket) has been described above, detailed description of specific matching process and principle is omitted here.

Referring to fig. 13, fig. 13 is a schematic view of a loading device 30 according to a second embodiment of the present invention, which is also another use state of the unloading apparatus 10 according to the present invention. The loading device 30 may be a new loader provided by the present invention, and includes a body 31 and a discharging device 32, it can be understood that the body 31 is substantially the same as the body 21 of the first embodiment, that is, the unloading device 32 may be the same as the unloading device 10 and the unloading device according to the modified embodiment thereof, in the same manner as the body 21 of the conventional loader without a bucket, the body 21 is directly connected to the unloading device 10 so that the unloading device 10 is mounted on the body 21, if the body 21 is directly connected to the support 11 of the unloading device 10 so that the unloading device 10 is mounted on the body 21, it should be understood that in the second embodiment, the locking mechanism 13 and the installation guide mechanism 14 of the unloading device 32 can be omitted, and the support 11 of the unloading device 32 can be directly connected and fixed with the machine body 21.

Referring to fig. 14 and 15, fig. 14 is a schematic structural view of a part of a transport apparatus (e.g., a box 40 of the transport apparatus) loaded with a cargo to be unloaded by the loading apparatus 20 or 30 of the unloading device 10, and fig. 15 is a top view of the box 40 of the transport apparatus shown in fig. 14. The box body 40 of the transportation device comprises a plurality of groups of movable box plates 41a which are symmetrically arranged, wherein each group of movable box plates 41a is designed to be double-opened, that is, each group of movable box plates 41a comprises two box plates, each movable box plate 41a is also adjacent to one movable box plate 41a of an adjacent group, and the opening directions of the two movable box plates are opposite. When the unloading device 10 is used to unload the cargo in the box body 40, a driving device (such as the body 21 of the loader in the first embodiment or the body 31 of the loader in the second embodiment) may be used to drive the unloading device 10, so that the cargo pushing member 12 of the unloading device 10 first pushes and unloads the box body area (i.e. the predetermined area 42) of each set of movable box plates 41 for the first time, after the first pushing and unloading, the cargo pushing member 12 of the unloading device 10 moves from one side of the box body 40 to the other side of the box body 40 through the box body 40, so that the support 11 of the unloading device 10 is substantially located in the box body 40 and corresponds to the predetermined area 42, the first pushing mechanism 15 substantially corresponds to the predetermined area 42, the first pushing mechanism 15 operates in the predetermined area 42, thereby pushing the residual cargo in the predetermined area 42, and then the residual cargoes in the predetermined area are unloaded from the box body, the two second pushing mechanisms 17 can correspond to the edge areas 43 on the two sides of the predetermined area 42, and further the two second pushing mechanisms 17 can work so as to push the cargoes in the edge areas 43 on the two sides of the predetermined area 42 (namely the area between the two groups of movable box plates) to the predetermined area 42, and then the cargoes are unloaded by the first pushing mechanism 15.

It should be noted that the second pushing mechanism 17 may push the goods in the edge region 43 toward the first pushing mechanism 15 to make the goods enter the predetermined region 42 where the first pushing mechanism 15 is located, and then the goods are pushed by the first pushing mechanism 15 to be unloaded, or push the goods away from the first pushing mechanism 15 to make the goods enter another adjacent predetermined region 42, and then the driving device drives the unloading device 10 to enter the adjacent predetermined region 42 from between another adjacent set of movable box plates 41, and then the goods are cleaned by the first pushing mechanism 15. Alternatively, the second pushing mechanism 17 may unload the cargo in the edge area 43 toward a side away from the predetermined area 42 (e.g., a side where the front door 41b or the rear door 41c is located), that is, from the front door 41b or the rear door 41 c.

In addition, when the unloading device 10 is in operation, the lifting driving assembly 155 can drive the first pushing member 154 and the second pushing member 174 to perform a lifting motion along the Z-axis, so as to adjust a distance or a contact area between the first pushing member 154 and the goods in the predetermined area 42 and a distance or a contact area between the second pushing member 174 and the goods in the edge area 43, thereby applying a suitable pushing force to the goods, which is beneficial to improving unloading efficiency, and in particular, when the bottom of the box 40 of the transportation apparatus (including the bottom of the predetermined area 42 and the bottom of the edge area 43) is uneven, the lifting driving assembly 155 is also beneficial to unloading the residual goods in the concave portion.

The third driving module 177 may also drive the second pushing member 174 to move in the X axis direction, the fourth driving module 178 may also drive the second pushing member 174 to move in the Y axis direction, and the fifth driving module 179 may drive the second pushing member 174 to rotate in the Z axis direction, so that not only the pushing range of the second pushing member 174 may be adjusted, but also the cargo in the edge region 43 may be pushed to the predetermined region 42, and further the first pushing mechanism 15 is utilized to completely unload the cargo.

In addition, as shown in fig. 14 and 15, in the box body 40 of the transportation device, the edge region 43 may be further provided with an auxiliary fixing device 44 for auxiliary fixing, such as tightening, of the cargo in the box body region corresponding to each set of the movable box plates 41 a. Specifically, the auxiliary fixing device 44 may be an "X" shaped zipper disposed in the edge area on one side or both sides of the predetermined area, or may also be a "pi" shaped zipper or other shaped zipper, and each of the zipper bodies may be a chain body formed by sequentially connecting metal rings. Because the second pushing mechanism 17 can be driven by the lifting driving assembly 155 to lift in the Z-axis direction, and can be driven by the third driving module 177, the fourth driving module 178 and the fifth driving module 179 to move back and forth in the X-axis direction, extend left and right in the Y-axis direction, and rotate around the Z-axis direction, the second pushing mechanism 17 can push the goods in the edge area 43 around the auxiliary fixing device 44, and the auxiliary fixing device 44 is prevented from shielding the second pushing mechanism 17.

It should be understood that the unloading device 10 is not limited to unloading the box body 40 having a plurality of sets of movable box plates as shown in fig. 14 and 15, but may also unload a box body having only one set or two sets of movable box plates 41a, and similarly, it is possible to achieve the effect of unloading the edge area on one side or both sides of the box body area corresponding to one set of movable box plates 41.

Compared with the prior art, in the unloading device 10 of the present invention, the first pushing mechanism 15 is located at the back side of the pushing member 12, the pushing member 12 can push to partially unload the goods in the predetermined area 42, and the first pushing mechanism 15 can push the residual goods in the predetermined area 42 after the pushing member 12 partially unloads the goods in the predetermined area 42, so as to reduce the action of driving the pushing member to perform multiple pushing and scraping, improve the unloading efficiency, and simplify the operation.

In addition, the first pushing mechanism 15 includes a first driving assembly 153 and a first pushing member 154, the first driving assembly 153 includes a first conveying member 160, the first pushing member 154 is disposed on the first conveying member 160, the first conveying member 160 is configured to drive the first pushing member 154 to reciprocate along a predetermined path and/or rotate along a predetermined axial direction to push the goods, and the pushing efficiency of the unloading device 10 can be effectively improved by the movement of the first conveying member 160.

Further, the second pushing mechanism 17 further pushes the goods in the edge area 43, so that the remaining goods in the predetermined area 42 and the edge area 43 can be pushed and unloaded, thereby reducing manual unloading and improving unloading efficiency.

Particularly, when the box 40 of the transportation device is long, although there is more residual cargo in the edge area 43 between two adjacent sets of movable box plates 41a after the cargo pushing member 12 is pushed for the first time, the residual cargo can be pushed by the second pushing mechanism 17 and further unloaded, thereby improving the unloading efficiency. In particular, due to the second pushing mechanism 17 located at the back side of the pushing member 12, the remaining cargo in the edge area 43 of the pushing member 12 can be pushed to be unloaded, so that the unloading device 10 can reduce manual unloading and improve unloading efficiency compared to a general bucket with a push-scrape unloading function and a bucket with auxiliary unloading function at both sides of the bucket.

It is understood that, for the container 40 having a plurality of sets of movable boxboards 41a, the second pushing mechanism 17 can push the goods in the edge area 43 to any one of the predetermined areas 42 on both sides, and then the goods can be pushed or scraped by the first pushing mechanism 15 and/or the pushing member 12 for unloading.

It will be appreciated that the pusher 12 may be similar in structure and function to the bucket of the conventional loader, i.e. pushing and unloading the cargo, and in one embodiment, since the first pushing mechanism 15 is further disposed behind the pusher 12, the first pushing mechanism 15 can further clean the residual cargo unloading the predetermined area 42, and the unloading device 10 of the present invention has higher efficiency compared to the conventional bucket. Further, the second pushing mechanism 17 may also be located at the back side of the pushing member 12 and located at the left side, the right side or both sides of the first pushing mechanism 15, for pushing the goods in the edge region 43 after the pushing member 12 partially unloads the goods in the predetermined region 42, so that all the remaining goods in the edge region 43 can be pushed to be unloaded.

In addition, the first pushing mechanism 15 and/or the second pushing mechanism 17 are located on the back side of the pushing member 12, after the pushing member 12 pushes the goods for the first time, the pushing member can pass through the box 40 from one side of the box 40 to move to the other side, at this time, the first pushing mechanism 15 and/or the second pushing mechanism 17 can be located in the box 40, and then the first pushing mechanism 15 and/or the second pushing mechanism 17 can unload the residual goods in the box 40, and the pushing member 12 does not need to be moved any more, which is obvious that the unloading device 10 is convenient to use and has high efficiency.

Further, the distance or contact area between the first pushing member 154 and the goods in the predetermined area 42 and the distance or contact area between the second pushing member 174 and the goods in the edge area 43 can be adjusted by the lifting driving assembly 155, so that a proper pushing force can be applied to the goods, which is beneficial to improving the unloading efficiency, and the lifting driving assembly 155 is also beneficial to unloading the residual goods in the concave portion especially when the bottom of the box body of the transportation equipment is uneven.

The first conveying member 160 may be provided with a plurality of first pushing plates 154a, and the first driving module 161 drives the first conveying member 160 to enable the plurality of first pushing plates 154a to sequentially push the goods, so that the goods pushing efficiency of the first pushing mechanism 15 can be effectively improved.

In the first pushing mechanism 15, the driver assembly 164 can drive the plurality of first conveying members 160 and the plurality of first pushing plates 154a simultaneously, and one driver is not used for one conveying member, so that the use of the driver can be reduced, the cost can be reduced, and the reduction of the overall size and weight of the discharge device 10 can be facilitated.

In the first pushing mechanism 15, each first pushing plate 154a may be connected to the plurality of first conveying members 160, so as to improve the stability of the connection between the first pushing plate 154a and the first conveying members 160 and prevent the first pushing plate 154a from twisting or tilting during the process of pushing the goods. When at least two (e.g., three) first driving wheels 163 may be sleeved on each first driving shaft 162, the first conveying element 160 may be supported by a plurality of first driving wheels 163 to provide a plurality of supporting points, so as to improve the stability of the first conveying element 160, and prevent the first pushing element 154 connected to the first conveying element 160 from twisting or tilting during the process of pushing the goods.

In one embodiment, the first driving wheel 163 is a chain wheel, the first transmission member 160 is a chain looped around the first driving wheel 163, and the chain wheel and the chain cooperate to provide a stronger driving force, so that the first pushing plate 154a can have a stronger pushing force.

In some embodiments, the second pushing mechanism 17 pushes the goods in the edge area 43 to the predetermined area 42, and then the first pushing mechanism 15 unloads the goods, so that the movable box plate 41a and the auxiliary fixing device 44 are prevented from being blocked, and the goods in the edge area 43 can be effectively unloaded. Of course, in a modified embodiment, when there is no shielding of the movable box plate 41a and the auxiliary fixing device 44, the second pushing mechanism 17 may directly unload the cargo in the edge area 43 from the front or the rear (such as the side where the pushing member 12 is located or the side where the locking mechanism 13 is located).

In the second pushing mechanism 17, each second pushing plate 174a may be connected to the plurality of second conveying members 170, so as to improve the stability of the connection between the second pushing plate 174a and the second conveying members 170, and prevent the second pushing plate 174a from twisting or tilting during the process of pushing the goods. When at least two second driving wheels 195 can be sleeved on each second driving shaft 194, the second conveying member 170 can be supported by a plurality of second driving wheels 195 to provide a plurality of supporting points, so that the stability of the second conveying member 170 is improved, and the second pushing member 174 connected to the second conveying member 170 is prevented from twisting or inclining in the process of pushing the goods.

In one embodiment, the second driving wheel 195 is a chain wheel, the second transmission member 170 is a chain looped around the second driving wheel 195, and the chain wheel and the chain cooperate to provide a stronger driving force, so that the second pushing plate 174a has a stronger pushing force.

In some embodiments, in the second fixing element 172, the first connecting portion 184 and the second connecting portion 185 include a base 186 and a roller 187 pivotally connected to the base 186, a surface of the roller 187 includes a first guiding structure 188 disposed along a rolling direction, and the first supporting rod 171b and the second supporting rod 171c are both provided with a second guiding structure 189 engaged with the first guiding structure 188, so that the second fixing element, the first supporting rod 171b and the second supporting rod 171c can lift the second pushing mechanism 17 in multiple directions under stress, and have a simple structure and a low cost, and in addition, lubricating oil can be added between the roller 187 and the first supporting rod 171b and the second supporting rod 171c, so that the two can be smoothly matched and the maintenance operation is convenient.

The second conveying member 170 may be provided with a plurality of second pushing plates 174a, and the second driving module 175 drives the second conveying member 170 so that the plurality of second pushing plates 174a sequentially push the goods, thereby effectively improving the goods pushing efficiency of the second pushing mechanism 17.

The third driving module 177 may also drive the second pushing member 174 to move in the X axis direction, the fourth driving module 178 may also drive the second pushing member 174 to move in the Y axis direction, and the fifth driving module 179 may drive the second pushing member 174 to rotate in the Z axis direction, so as to not only adjust the pushing range of the second pushing member 174, but also facilitate the goods in the edge region 43 to be pushed to the predetermined region 42, facilitate the second pushing mechanism 17 to bypass the auxiliary fixing device 44 to push the goods in the edge region 43, and avoid the auxiliary fixing device 44 from shielding the operation of the second pushing mechanism 17. In addition, the fourth driving module 178 can also drive the second pushing member 174 to move in the Y-axis direction, so that when the pushing member 12 of the unloading device 10 pushes and unloads the goods, the second pushing member 174 (as well as the second driving module 175, the fifth driving module 179, the second fixing frame 191, and the like) is retracted into the supporting member 11 or the back of the pushing member 12, for example, does not protrude from both sides of the supporting member 11 or the pushing member 12, thereby preventing the second pushing member 174 and the like from being caught at the movable box plate 41a of the box 40 of the transportation apparatus and being unable to enter the box 40 for unloading the goods.

Further, the plurality of first pushing plates 154a and/or the plurality of second pushing plates 174a may be pushing plates alternately arranged in length, so that distances or contact areas with goods are different, so that goods with different heights may be sequentially pushed, and jamming of the goods with the first pushing plates 154a and/or the plurality of second pushing plates 174a during pushing of the goods may be reduced to a certain extent. The plurality of first pushing plates 154a and/or the plurality of second pushing plates 174a may also be a plurality of pushing plates arranged alternately in soft and hard states, so that the pushing force to the goods may be different, the goods with different weights or sizes may be pushed, and the jamming of the goods with the first pushing plates 154a and/or the second pushing plates 174a during the pushing process may also be reduced to a certain extent. The first pushing plates 154a and/or the second pushing plates 174a may also be a plurality of pushing plates alternately arranged in length and in combination with the alternate arrangement of hardness and softness, for example, the long pushing plates are also soft pushing plates, and the short pushing plates are hard pushing plates, so that the pushing force on the goods can be different, and the goods with different heights, weights and sizes can be pushed, and the jamming of the goods with the first pushing plates 154a and/or the second pushing plates 174a during the pushing process can be reduced.

Further, in the first embodiment and in use, the unloading device 10 can be mounted on the bucket 22 of an existing loader, so that the unloading device 10 can be easily detached from the loader without modifying the existing loader, and is very convenient to use, transport and the like. In addition, the locking mechanism 13 can automatically drive the hook 133 to lock or disengage the external object (e.g., the bucket), so that the unloading device 10 can be conveniently mounted and dismounted, i.e., the unloading device 10 can be quickly dismounted without manual connection or dismounting, thereby improving the production efficiency. The installation guide 14 can also guide and align with the external object when the discharge device 10 is installed, so that the installation of the discharge device 10 is facilitated, the installation guide 140, the locking member 144 and/or the extension rod 117 can further lock with the external object (e.g., clamp against the inner surface of the external object), so as to strengthen the connection between the discharge device 10 and the external object, and improve the stability and reliability of the discharge device 10 and the loading equipment 20 using the discharge device 10.

It is understood that in a modified embodiment, the discharge device 10 may omit the second pushing mechanism 17, as shown in fig. 16, and in the modified embodiment, the discharge device 10 ' includes a support 11 ', a cargo pushing member 12 ', a locking mechanism 13 ', a mounting guide mechanism 14 ', a first pushing mechanism 15 ', and the support 11 ', the cargo pushing member 12 ', the locking mechanism 13 ', the mounting guide mechanism 14 ', and the first pushing mechanism 15 ' are substantially the same as the support 11, the cargo pushing member 12, the locking mechanism 13, the mounting guide mechanism 14, the first pushing mechanism 15, and the second pushing mechanism 17 in the embodiment shown in fig. 1 to 13, and thus, the description thereof is omitted. When the unloading device 10 'of the modified embodiment shown in fig. 16 is used, after the first pushing device (e.g., a bucket of a loader) pushes the first pushing device to at least partially unload the load in the predetermined area 42, the first pushing mechanism 15' pushes the remaining load in the predetermined area 42, so that the operation of driving the pushing member to push and scrape the load a plurality of times can be reduced, the unloading efficiency can be improved, and the operation can be simplified.
